DESCRIPTION
An SDL_CD structure is returned by SDL_CDOpen. It represents an opened
CDROM device and stores information on the layout of the tracks on the
disc.
A frame is the base data unit of a CD. CD_FPS frames is equal to 1 sec-
ond of music. SDL provides two macros for converting between time and
frames: FRAMES_TO_MSF(f, M,S,F) and MSF_TO_FRAMES.
EXAMPLES
int min, sec, frame;
int frame_offset;
FRAMES_TO_MSF(cdrom->cur_frame, &min, &sec, &frame);
printf("Current Position: %d minutes, %d seconds, %d frames
", min, sec, frame);
frame_offset=MSF_TO_FRAMES(min, sec, frame);
